Abstract-The cross sections for nuclide production in thin93 Nb and nat Ni targets irradiated by 0.04-to 2.6-GeV protons have been measured by direct γ spectrometry using two γ spectrometers with the resolutions of 1.8 and 1.7 keV in the 60 Co 1332-keV γ line. As a result, 1112 yields of radioactive residual nuclei have been obtained. The 27 Al(p, x) 22 Na reaction has been used as a monitor reaction. The experimental data have been compared with the MCNPX (BERTINI, ISABEL), CEM03.02, INCL4.2, INCL4.5, PHITS, and CASCADE07 calculations.

“…Predictions of produced quantities are therefore also integrally dependent upon the accuracy of nuclear data repositories to account for the contributions from "indirect reactions" induced by secondary particles of lower energy produced during the initial "direct reactions" and parent isotopes' decay. The two methods of isotope formation, by the decay of parents and by direct reaction, are described with the terms "cumulative" and "independent", respectively [6] and designated using the labels "c" and "i". When parents' decay is incompletely accounted for in the data, cross sections are described with the label "c*".…”

Cross sections from proton irradiation of thorium at 800 MeV

et al. 2013

View full text Add to dashboard Cite

Nuclear formation cross sections are reported for 65 nuclides produced from 800-MeV proton irradiation of thorium foils. These data are useful as benchmarks for computational predictions in the ongoing process of theoretical code development and also to the design of spallation-based radioisotope production currently being considered for multiple radiotherapeutic pharmaceutical agents. Measured data are compared with the predictions of three MCNP6 event generators and used to evaluate the potential for 800-MeV productions of radioisotopes of interest for medical radiotherapy. In only a few instances code predictions are discrepant from measured values by more than a factor of two, demonstrating satisfactory predictive power across a large mass range. Similarly, agreement between measurements presented here and those previously reported is good, lending credibility to predictions of target yields and radioimpurities for high-energy accelerator-produced radionuclides. 25.40.Sc, 87.56.bd PACS number(s):

Analysis of the main nuclear-physical characteristics of the interaction of proton beams with heavy metal targets

It is shown that the concept of relativistic heavy-nuclear energy is untenable. Using a large group of different experiments in the proton energy range 0. it is demonstrated that the high-energy hadron transport program SHIELD, which is based on modern nuclear models, has predictive power. The interaction of protons with energy ranging from 0.1 to 100 GeV with a simple model system target + blanket, containing heavy elements (lead, thorium, depleted and enriched uranium), is examined. The energy release, neutron production, and production of fissile isotopes in the system are calculated. It is found that for all values of the proton energy which are considered the useful yield of energy in weakly fissile media is inadequate (thorium, depleted uranium) and is completely absent in non-fissile media (lead). A blanket containing enriched uranium will be necessary in order to use the scheme for useful production of energy. In this variant, the optimal proton energy is 1-3 GeV, which corresponds to the conventional concept of electronuclear facilities whose main purpose is to transmute nuclear wastes and produce electricity at the same time.The concept of commercial production of energy using accelerators to accelerate heavy charged particles has been discussed since the beginning of the 1950s. According to this concept, a beam of protons or ions with sufficiently high energy should generate a large number of neutrons on interacting with a heavy target. Facilities which function according to this principle are said to be electronuclear facilities. The accelerator must be a high-current accelerator in order to produce more neutrons, and for this reason the target is a complicated technical system. An advantage of electronuclear facilities over conventional nuclear reactors is that there is no possibility of reactivity accidents.
